2015-06-01Merge branch 'dt/cat-file-follow-symlinks'Libravatar Junio C Hamano1-6/+45
"git cat-file --batch(-check)" learned the "--follow-symlinks" option that follows an in-tree symbolic link when asked about an object via extended SHA-1 syntax, e.g. HEAD:RelNotes that points at Documentation/RelNotes/2.5.0.txt.

"git merge FETCH_HEAD" learned that the previous "git fetch" could be to create an Octopus merge, i.e. recording multiple branches that are not marked as "not-for-merge"; this allows us to lose an old style invocation "git merge <msg> HEAD $commits..." in the implementation of "git pull" script; the old style syntax can now be deprecated. * jc/merge: merge: deprecate 'git merge <message> HEAD <commit>' syntax merge: handle FETCH_HEAD internally merge: decide if we auto-generate the message early in collect_parents() merge: make collect_parents() auto-generate the merge message merge: extract prepare_merge_message() logic out merge: narrow scope of merge_names merge: split reduce_parents() out of collect_parents() merge: clarify collect_parents() logic merge: small leakfix and code simplification merge: do not check argc to determine number of remote heads merge: clarify "pulling into void" special case t5520: test pulling an octopus into an unborn branch t5520: style fixes merge: simplify code flow merge: test the top-level merge driver
2015-05-19Merge branch 'nd/diff-i-t-a'Libravatar Junio C Hamano1-0/+1
After "git add -N", the path appeared in output of "git diff HEAD" and "git diff --cached HEAD", leading "git status" to classify it as "Changes to be committed". Such a path, however, is not yet to be scheduled to be committed. "git diff" showed the change to the path as modification, not as a "new file", in the header of its output. Treat such paths as "yet to be added to the index but Git already know about them"; "git diff HEAD" and "git diff --cached HEAD" should not talk about them, and "git diff" should show them as new files yet to be added to the index. * nd/diff-i-t-a: diff-lib.c: adjust position of i-t-a entries in diff
2015-05-19clone: call transport_set_verbosity before anything else on the newly ↵Libravatar Mike Hommey1-2/+2
created transport Commit 2879bc3 made the progress and verbosity options sent to remote helper earlier than they previously were. But nothing else after that would send updates if the value is changed later on with transport_set_verbosity. While for fetch and push, transport_set_verbosity is the first thing that is done after creating the transport, it was not the case for clone. So commit 2879bc3 broke changing progress and verbosity for clone, for urls requiring a remote helper only (so, not git:// urls, for instance).

2015-05-18clean: only lstat files in pathspecLibravatar David Turner1-3/+3
Even though "git clean" takes pathspec to limit the part of the working tree to be cleaned, it checked the paths it encounters during its directory traversal with lstat(2), before checking if the path is within the pathspec. Ignore paths outside pathspec and proceed without checking with lstat(2). Even if such a path is unreadable due to e.g. EPERM, "git clean" should not care.

2015-05-05hash-object --literally: fix buffer overrun with extra-long object typeLibravatar Eric Sunshine1-3/+1
"hash-object" learned in 5ba9a93 (hash-object: add --literally option, 2014-09-11) to allow crafting a corrupt/broken object of unknown type. When the user-provided type is particularly long, however, it can overflow the relatively small stack-based character array handed to write_sha1_file_prepare() by hash_sha1_file() and write_sha1_file(), leading to stack corruption (and crash). Introduce a custom helper to allow arbitrarily long typenames just for "hash-object --literally".

The die() / error() / warning() helpers put a fatal: / error: / warning: prefix in front of the error message they print describing the message's severity, which users are likely to be accustomed to seeing these days. This change will also be useful when marking the message for translation: the argument to error() includes no newline at the end, so it is less fussy for translators to translate without lines running together in the translated output. While we're here, start the error messages with a lowercase letter to match the usual typography of error messages. A quick web search and a code search at codesearch.debian.net finds no scripts trying to parse these error messages, so this change should be safe.

2015-05-03blame: CRLF in the working tree and LF in the repoLibravatar Torsten Bögershausen1-0/+1
A typical setup under Windows is to set core.eol to CRLF, and text files are marked as "text" in .gitattributes, or core.autocrlf is set to true. After 4d4813a5 "git blame" no longer works as expected for such a set-up. Every line is annotated as "Not Committed Yet", even though the working directory is clean. This is because the commit removed the conversion in blame.c for all files, with or without CRLF in the repo. Having files with CRLF in the repo and core.autocrlf=input is a temporary situation, and the files, if committed as is, will be normalized in the repo, which _will_ be a notable change. Blaming them with "Not Committed Yet" is the right result. Revert commit 4d4813a5 which was a misguided attempt to "solve" a non-problem. Add two test cases in t8003 to verify the correct CRLF conversion.

2015-04-29merge: deprecate 'git merge <message> HEAD <commit>' syntaxLibravatar Junio C Hamano1-0/+1
We had this in "git merge" manual for eternity: 'git merge' <msg> HEAD <commit>... [This] syntax (<msg> `HEAD` <commit>...) is supported for historical reasons. Do not use it from the command line or in new scripts. It is the same as `git merge -m <msg> <commit>...`. With the update to "git merge" to make it understand what is recorded in FETCH_HEAD directly, including Octopus merge cases, we now can rewrite the use of this syntax in "git pull" with a simple "git merge FETCH_HEAD". Also there are quite a few fallouts in the test scripts, and it turns out that "git cvsimport" also uses this old syntax to record a merge. Judging from this result, I would not be surprised if dropping the support of the old syntax broke scripts people have written and been relying on for the past ten years. But at least we can start the deprecation process by throwing a warning message when the syntax is used. With luck, we might be able to drop the support in a few years.

2015-04-29merge: handle FETCH_HEAD internallyLibravatar Junio C Hamano1-34/+72
The collect_parents() function now is responsible for 1. parsing the commits given on the command line into a list of commits to be merged; 2. filtering these parents into independent ones; and 3. optionally calling fmt_merge_msg() via prepare_merge_message() to prepare an auto-generated merge log message, using fake contents that FETCH_HEAD would have had if these commits were fetched from the current repository with "git pull . $args..." Make "git merge FETCH_HEAD" to be the same as the traditional git merge "$(git fmt-merge-msg <.git/FETCH_HEAD)" $commits invocation of the command in "git pull", where $commits are the ones that appear in FETCH_HEAD that are not marked as not-for-merge, by making it do a bit more, specifically: - noticing "FETCH_HEAD" is the only "commit" on the command line and picking the commits that are not marked as not-for-merge as the list of commits to be merged (substitute for step #1 above); - letting the resulting list fed to step #2 above; - doing the step #3 above, using the contents of the FETCH_HEAD instead of fake contents crafted from the list of commits parsed in the step #1 above. Note that this changes the semantics. "git merge FETCH_HEAD" has always behaved as if the first commit in the FETCH_HEAD file were directly specified on the command line, creating a two-way merge whose auto-generated merge log said "merge commit xyz". With this change, if the previous fetch was to grab multiple branches (e.g. "git fetch $there topic-a topic-b"), the new world order is to create an octopus, behaving as if "git pull $there topic-a topic-b" were run. This is a deliberate change to make that happen, and can be seen in the changes to t3033 tests. Signed-off-by: Junio C Hamano <gitster@pobox.com>
